GUIDE- OILER.

Specication of Lette-rs Patent.

Patented Feb. 18, 1919.

Application led October 19, 1918. Serial No. 258,781.

T0 all whom t may concern:

Be it known that I, EDMUND WEIGELE, a citizen of the United States ofAmerica, residing at Bergenlield, Bergen county, State of New Jersey,have invented certain new and useful Improvements in Guide-Rail Oilers,of which the following is a full, clear, and exact description.

This invention relates to improvements in oiling devices particularlyarranged to apply a lubricant to guide-rails for elevators. My improvedoiling device is desi ned to apply, or cause to be applied, a lubrlcantin small quantities to be spread or applied to the wearing surfaces ofthe rails by the guide-shoes.

My improved device is adapted to be attached to the upper end orterminal of'a guide-rail and is in the form of a reservoir from whichthe lubricant is fed, or delivered by wicks in combination with flexibleconductors or feeders. In other words, the wicks feed the lubricant tothe feeders by capillary attraction, the feeders in turn acting asconveyers for the lubricant to trickle dojlvn by gravity to and alongthe guiderai I will now proceed to describe my invention in detail, thenovel features of which will be pointed out in the appended claims,reference being had to the accompanying drawings, forming part hereof,wherein:-

Figure 1 is a perspective view of the upper portion of an elevatorguide-rail having my improved oiling device applied thereto;

Fig. 2 is a top plan view thereof;

Fig-3 is to top plan view of the reservoir, the cover being removed,andthe rail being broken away;

Fig. 4 is a vertical sectional View, the section being takenl on a line4-4 in Fig.` 2; and

Fig. 5 is an enlarged sectional view of one of the wick-tubes, alsoillustrating the secondary feeder'carried thereby.

In the drawing a portion of a guide-rail, for an elevator', is indicatedby 6, said guide rail consisting of a base-member 7 and a guide 8whichis engaged by a shoe on an elevator. For the purpose of applying alubricant to the wearing surfaces 8a of the guide 8, I provide anoil-reservoir 9 having a cover l() hinged thereto at 11. The reservoir 9carries a web 12 having a recess or jaw 13 to receive the guide 8 of theguiderail. 4In other words, the reservoir is secured to the guide-railat its upper end, the recess or jaw 13 being formed to receive the upperend of the guide 8. The reservoir 9 rests upon the upper end 14 of thisguide a' and is secured thereto by atap-bolt 15. As can be seein in Fig.2, the cover 10 is recessed at 16 to clear the head of tap-bolt l5. Therecess 13 is virtually a slot in the web 12 having an upper wall whichrests upon the upper end 0f the guide 8 and a vertical wall 17 whichrests against the face 18 of the guide 8. The bolt 15 passes through theupper wall of the slot 13, as can be seen in Fig. 4.

To convey oil from the reservoir 9 to the i i surfaces 8 of the guide 8,I provide (in this instance) three ducts or tubes 19, 20 and 21,

each carrying a wick 22 and a flexible resilient feeder 23, betterillustrated in Fig. 5. One end of each wick is immersed in the oil',indicated by 24 (Fig. 4), while the other end is located in its ductadjacent the lower end thereof. In other words, each wick projectsdownwardly in its duct to a point adjacent the point of connection ofsaid duct and a spout 24El carriedthereby, the purpose being to causethe wicks to convey oil, by capillary' attraction, to the feeders 23,instead of directly to the rail or guide 8. By this means, I am able toprevent a surplus amount of oil being delivered. Each duct and its spoutcarries a feeder 23, which consists of a strip of flexible material,such as spring steel, having a hook 25 to engage the upper end 26 of itsduct. The oil delivered or fed to the feeders by the wicks willgravitate to the surfaces 8a of the guide.

Owing to the vibration incident to the elevator mechanism, the oil willgradually travel downwardly along the feeders to the rail. As thefeeders 23 are made of relatively thin flexible material, they willvibrate with the elevator mechanism, which includes the guide-1ails:hence the feeding of the oil will be greatly facilitated. As can be seenin Fig. 4, the lower end of the feeders will rest in contact with theguiderail. The feeders being flexible, accuracy of workmanship inapplying the reservoir to the rail is not necessary, as said feederswill accommodate themselves to contact with the rail. As will be seen,the spouts 24a do not contact with the Guide 8.

The ducts, and their guides, are preferably removable, said ducts beingprovided Sli ffii e.,

with threads 27 to engage threads formed in openings in the bottom oithe reservoir 9, a loclenilt 23 being employed to hold the ducts inplace.

What i claim es my invention is l. ln e. lubricating device, anoil-reservoir, e. duct leading therefrom, e etiible resilient feeder`Within said duct and projecting therefrom, and e wick to convey oil fromthe reservoir te seid feeder.

2. ln L lubricating device, :i reservoir, e duct carried thereby, andprojecting therefrom, a 'Wick carried by the duct and extendingn intoseid reservoir adapted to convey oil by capillary attraction from seidreservoir to the interior oi said duct, e, Viellible resilient eederalso carried by seid duct end projecting from one end thereof, and ehook carried by the feeder to releasebly engage the upper end of theduct.

3. A e source oi oil suppiy, a Wick carried b v 'the ductJ extendingpartly therethrough, the other end of seid Wick being adapted; to beimmersed in the oil, and e, flexible resilient feeder carried by theduct extendizi" :from the point Within the duct Where seid wick stops toe point beyond the end of seid duct.

4. In a. lubricating device, a reservoir, e., duct carried thereby andprojecting therefrom, seid reservoir being' provided with e recess toreceive the upper end oit' an elevator-guide-reil, said recess having enupper Well, to rest upon the upper edge of said rail, e bolt passingthrough the upper Well of seid recess and engaging said guide-rail, andmeans to conve),7 oil from the reservoir into seid duct.
